2012 Volkswagen Jetta TDI, 4D Wagon, Standard TransSECTION General Information
WARNING: This page is about a different car, the 2014 Volkswagen Jetta and 2013 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

Transmission 

  • The Electro-Drive Drive Motor -V141- transfers the engine torque to the double clutch. The Electro-Drive Drive Motor -V141- and the dual clutch are connected via splines. The Electro-Drive Drive Motor -V141- has a disengagement clutch. The decoupler in Electro-Drive Drive Motor -V141- separates the internal combustion engine from the Electro-Drive Drive Motor -V141-.
  • The transmission is built like a 7-speed manual transmission. The alternating hydraulic actuation of the two dry multi-plate clutches permits operation similar to that of an automatic transmission. This means the gears are automatically or manually shifted via the Tiptronic mode. Clutch pedal is not available.
  • Both clutches are open when the ignition is off. 1st gear on sub-transmission 1 and reverse gear on sub-transmission 2 are engaged.

Some Vehicles Have A Cover Over the Engaging Levers.

Selector Mechanism

In contrast to the automatic transmission, the selector lever position is no longer transmitted mechanically to the transmission via the selector lever cable and Multi-Function Transmission Range. Selector lever positions and shifts are transmitted via a separate control module in the selector mechanism to the transmission control module via the CAN-Bus. The shifter occurs without a cable. The selector lever cable is mechanically brought into the park brake in the selector lever position "P".

Transmission Fluid 

Fig 4: Locating Fluid Systems

The 7-speed DSG® transmission has two separate, different fluid systems. One for the transmission fluid -arrow A- and one for the hydraulic fluid -arrow B-.

Only transmission fluids specific to the DSG® transmission 0CG may be used. They are available as a replacement part. Using other oils can lead to function problems or can even cause the transmission to fail, for the specification.

Do not mix any >>additives<< into the oil.

Do not re-use drained transmission fluid.

CAUTION:

Be very careful when working with transmission fluid. Dispose of drained transmission fluid correctly.

It is not possible to check the transmission fluid level in the transmission. The only way to adjust the transmission fluid level is to replace the transmission fluid, for example, if the transmission is leaking fluid, refer to TRANSMISSION FLUID, DRAINING AND FILLING .
